SCRog or LST you can do with a single plant. Keeps them short with an even canopy if youre good. If i were you id go to walmart and get 4 pieces of science fair/ project board from walmart. They are cheap and flat white. Youd be amazed at how much brighter that 400 would be with white background. My whole object with growing is trying to utilize every bit of light i can. Get your money out of that light. Its just what id do for a temporary set up.

Oh yea good job. The two look real healthy:thumbsup:
